Abstract: 【Objectives】To identify priority protection areas (PPAs) and the protection gaps of marsh wetlands in Yunnan province and to provide scientific guidelines for the protection and management of marsh wetlands.【Methods】Taking peat marshes as the determination standard, the PPAs of marsh wetlands in Yunnan province were determined by hot spot analysis, and the protection gaps of PPAs were identified by ArcGIS.【Results】There were 1 491.84 hm² PPAs in Yunnan province which were mainly distributed in northwest, northeast, and southeast. Among them, there were 600.79 hm² in Diqing Prefecture, 225.06 hm² in Lijiang City, 114.14 hm² in Nujiang Prefecture, 308.58 hm² in Honghe Prefecture, and 138.00 hm² in Zhaotong City. There were 932.58 hm² of the PPAs covered by natural protected areas. There were still 559.26 hm² of protection gaps, mainly 225.06 hm² distributed in Lijiang City, 150.40 hm² in Diqing Prefecture, and 138.00 hm² in Zhaotong City. 【Conclusions】Suggestions were proposed including applying for national or provincial important wetlands in the vacant areas of wetland protection in Yongshan County, Yulong County, and Shangri-La City, expanding Yunnan Baima Snow Mountain National Nature Reserve.
